Abstract

A door hold open and controlled release mechanism is designed for usage in a doorway system having an inner door, an outer door and a door closer. It includes a catch mechanism and a catch release mechanism. The catch mechanism holds the outer door, typically a screen door or storm door, in an open position against the closing tendency of the door closer. Movement of the inner door to an open position then toward a closed position triggers the catch release mechanism which allows the outer door to close under the urging of the door closer.
